2 Claims.

This invention relates to rubber door stops.

Wedge shaped rubber door stops adapted to be inserted under the lower edge of a door to prevent undesired swinging are well known, but

so far as I am aware, all such door stops have,

to be placed right side up for effective use. That is, such door stops have a bottom face adapted to lie flat on the floor and a wedge face to engage the door, and in use such door stops have to be placed with their respective faces properly positioned to operate efiectively.

It is an object of the present invention to provide a door stop which will operate effectively in any position in which it is laid on the floor.

Other objects and advantages of the invention will appear hereinafter.

A preferred embodiment of the invention selected for purposes of illustration is shown in the accompanying drawing, in which,

Figure 1 is an end View.

Figure 2 is a top plan view.

Figure 3 is a section on the line 3-3 of Figure 2.

Referring to the drawing, the door stop is in the form of a pyramid and preferably is made with an odd number (three as shown in the drawing) of fiat triangular faces or sides I, with the edges between adjacent faces flattened somewhat to provide additional rather narrow faces 2 of considerably less area than the faces I, said narrow faces having parallel longitudinal edges.

Each of the narrow faces is located opposite one of the faces 1. Because of the narrowness of the faces 2 the door stop will not lie on these faces, but will roll over, when dropped on the floor, to lie on one of the faces I, so that it is always in position to be pushed under the door, with one of the narrow faces uppermost and in position to engage the lower edge of the door. The narrow faces are also of advantage in that the area of engagement with the door is less than in most types of door stops, and consequently the pressure is more concentrated and a better holding engagement is effected.

The door stop may be made of molded rubber of any suitable composition, and may be either solid, as shown, or may be cored out, if desired.

It will be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

I claim as my invention:

1. A rubber door stop in the form of a pyramid, said stop having a plurality of relatively wide faces and a plurality of relatively narrow faces alternating therewith with each of the narrow faces lying opposite one of the wider faces.

2. A rubber door stop in the form of a pyramid, said stop having a plurality of triangular faces and a plurality of faces having parallel edges alternating with said triangular faces.
